Ferret did work at BIS on both Jefferson and Van Buren (The Black Hound and Fallout 3). On F3 he was designing the highly nutty (but cool) Brotherhood of Steel/Circle of Steel stuff.

I'm now the acting lead designer on NWN2.

In addition, NWN2News is reporting that Ferret is no longer with Obsidian Entertainment at all. While I'm confident that Josh will do a helluva job on the game, I still worry that a major change like this so far into the game's development could cause a major delay or other unforseen troubles.
